Mixed feelings:
- Hopytal was a festival of guessing and false hints, it's really notable how guessy this challenge was.
- That heap pwn was really nonsensical, it had an artificial bug which made no sense. There was a global array `int is_ptr_freeable[10]` which wasn't actually an array, but something like "inlined array" with one entry replaced with `char buf[4]` to which the input was read. And there was off-by-one on that read. How do you even make such a construction in the source? I guess only when you're a CTF challenge autor and have no good ideas?
- Most of other challenges were ok - not great, but not bad.
- We lost one place because someone submitted a flag _after the CTF ended_. We asked organizers about this and they replied: "The CTF started around 2 minutes late and allowed to be played the whole 24h. Because of this, the flag submission was still open for a small amount of time after 12:00 UTC. Since your CTF experience was under 24h the 2 flags sent between 12:00 and 12:02 are accepted.". It's really great that the timer on the scoreboard reached 0 exactly at 12:00 UTC and yet it seems the CTF was still running...
